NHTSA's VIN data lists these trims for the 2021 Avalon. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.
Owners have filed 27 complaints with NHTSA about the 2021 Avalon. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year
Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.
NHTSA lists 2 recall campaigns for the 2021 Avalon over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Avalon, Avalon Hybrid, Corolla, Highlander, Highlander Hybrid, RAV4, RAV4 Hybrid, Lexus ES350, Lexus RX350, Lexus RX450H, 2021 Sienna Hybrid, Lexus ES250, 2020-2022 Camry, Camry Hybrid, and ES300H vehicles. A short circuit may develop in the Occupant Classification System (OCS) sensor, preventing the front passenger air bag from deploying.
Risk: An air bag that does not deploy during a crash increases the risk of injury.
Remedy: Dealers will inspect and replace the sensor as necessary, free of charge. Interim letters notifying owners of the safety risk were mailed in February 2024. Some final remedy owner letters were mailed October 31, 2024. Letters will continue to be mailed in phases through January 2026. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 23TB15/23TA15 Lexus 23LB03/23LA03.
Toyota Motor Engineering & Manufacturing (Toyota) is recalling certain 2020-2021 Toyota Avalon and 2020 Avalon Hybrid, RAV4, and RAV4 Hybrid vehicles. Breakaway pins within the steering column, designed to absorb energy and reduce injury during a crash, could have been damaged during production, possibly affecting the performance of the driver's air bag in the event of a crash. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, "Occupant Crash Protection."
Risk: In the event of a crash, an air bag that does not perform as designed can increase the risk of injury.
Remedy: Toyota will notify owners, and dealers will replace the steering column, free of charge. The recall began December 18, 2020. Owners may contact Toyota customer service at 1-800-331-4331. Toyota's number for this recall is 20TB17/20TA17.

NHTSA defect investigations
Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.
